a.Ta có \(\dfrac{2323}{9999}=\dfrac{2323:101}{9999:101}=\dfrac{23}{99}\)
\(\dfrac{232323}{999999}=\dfrac{232323:10101}{999999:10101}=\dfrac{23}{99}\)
Vậy\(\dfrac{23}{99}=\dfrac{2323}{9999}=\dfrac{232323}{999999}\)(Vì cùng bằng \(\dfrac{23}{99}\))
\(\dfrac{2323}{9999}=\dfrac{2323:101}{9999:101}=\dfrac{23}{99}\)
\(\dfrac{232323}{999999}=\dfrac{232323:10101}{999999:10101}=\dfrac{23}{99}\)
cứ thế mà làm
a\(\dfrac{2323}{2323}=\dfrac{2323:101}{9999:101}=\dfrac{23}{99}\)
\(\dfrac{232323}{999999}=\dfrac{232323:10101}{999999:10101}=\dfrac{23}{99}\)
b\(\dfrac{9909}{8808}=\dfrac{9909:1101}{8808:1101}=\dfrac{9}{8}\)
\(\dfrac{29727}{26424}=\dfrac{29727:3303}{26424:3303}=\dfrac{9}{8}\)
\(\dfrac{39636}{35232}=\dfrac{39639:4404}{35232:4404}=\dfrac{9}{8}\)
